关于git和github的介绍，我这边不多说。
使用在windows下使用git，需要配置环境变量，也可以使用git自带的终端工具。
，打开git bash
laoni@DESKTOP-TPPLHIB MINGW64 ~ (master) $ cd c:/laoni laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni $ dir AutomatedMonitor bak Mr.blue PycharmProjects laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni $ cd PycharmProjects/
界面和linux的终端相识，首先需要进行初始化，也就是配置个人信息：
使用git help可以查看git相关命令，也可以通过git help command指定命令查询。
$ git help usage: git [--version] [--help] [-C <path>] [-c name=value] [--exec-path[=<path>]] [--html-path] [--man-path] [--info-path] [-p | --paginate | --no-pager] [--no-replace-objects] [--bare] [--git-dir=<path>] [--work-tree=<path>] [--namespace=<name>] <command> [<args>] These are common Git commands used in various situations: start a working area (see also: git help tutorial) clone Clone a repository into a new directory init Create an empty Git repository or reinitialize an existing one work on the current change (see also: git help everyday) add Add file contents to the index mv Move or rename a file, a directory, or a symlink reset Reset current HEAD to the specified state rm Remove files from the working tree and from the index examine the history and state (see also: git help revisions) bisect Use binary search to find the commit that introduced a bug grep Print lines matching a pattern log Show commit logs show Show various types of objects status Show the working tree status grow, mark and tweak your common history branch List, create, or delete branches checkout Switch branches or restore working tree files commit Record changes to the repository diff Show changes between commits, commit and working tree, etc merge Join two or more development histories together rebase Reapply commits on top of another base tip tag Create, list, delete or verify a tag object signed with GPG collaborate (see also: git help workflows) fetch Download objects and refs from another repository pull Fetch from and integrate with another repository or a local branch push Update remote refs along with associated objects 'git help -a' and 'git help -g' list available subcommands and some concept guides. See 'git help <command>' or 'git help <concept>' to read about a specific subcommand or concept.
使用git config --global user.name "XXX" 和git config --global user.email "XXX@XX.com"可以添加用户名和邮箱，
使用 git config --unset --global user.name 可以取消用户名配置，
使用 git config --list 查看所有可用的配置信息。
laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/github_test $ git config --global user.name 'LaoNiNi' laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/github_test $ git config --global user.email "laonivv@163.com" laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/github_test $ git config --unset --global user.name laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/github_test $ git config --list core.symlinks=false core.autocrlf=true core.fscache=true color.diff=auto color.status=auto color.branch=auto color.interactive=true help.format=html rebase.autosquash=true http.sslcainfo=F:/pythonfile/Git/mingw64/ssl/certs/ca-bundle.crt diff.astextplain.textconv=astextplain filter.lfs.clean=git-lfs clean -- %f filter.lfs.smudge=git-lfs smudge -- %f filter.lfs.required=true filter.lfs.process=git-lfs filter-process credential.helper=manager user.email=laonivv@163.com filter.lfs.clean=git-lfs clean %f filter.lfs.smudge=git-lfs smudge %f filter.lfs.required=true
git区分工作区和版本库
对于项目根目录github_test目录来说，这就是工作区。
使用 git init 命令进行初始化，之前的config配置，需要初始化才能生效，config配置信息存在.git/config文件
laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/github_test
$ git init
Initialized empty Git repository in C:/laoni/PycharmProjects/github_test/.git/
PS：如果对git不熟悉的话，建议不要对。git目录下的文件进行修改。
使用git status查看当前git状态，Untracked files（未监视的文件，未被跟踪文件）也就是没有存到暂存区（上面截图的版本库下的index部分）的文件，使用git add index.html 把文件添加到暂存区。
laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/github_test (master) $ git status On branch master Initial commit Untracked files: (use "git add <file>..." to include in what will be committed) index.html nothing added to commit but untracked files present (use "git add" to track) laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/github_test (master)
laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/github_test (master)
$ git add index.html
laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/github_test (master)
$ git status
On branch master
Initial commit
Changes to be committed:
(use "git rm --cached <file>..." to unstage)
new file: index.html
把index.html文件添加到暂存区后，需要把文件从暂存区添加到branch master分支上，一般一个项目会有个主分支（一般叫master），使用git commit提交，会提示说明下这次的提交注释，再用git status查看，提示在当前主分支，没有需要commit的文件，工作区很干净。
laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/github_test (master) $ git commit [master (root-commit) 04c94a8] 添加一个文件index.html 1 file changed, 0 insertions(+), 0 deletions(-) create mode 100644 index.html laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/github_test (master) $ git status On branch master nothing to commit, working tree clean
实际上不管是暂存区还是分支上的文件，都存储在objects里面，暂存区和分支上的文件只是一个指向，目录树，有点像windows里的快捷方式了，这个需要理清。
